Abstract: In this paper, a singularly perturbed boundary value problem for second order self-adjoint ordinary differential equation is discussed.A class of variational difference schemes is constructed by the finite element method.Uniform convergence about small parameter is proved under a weaker smooth condition with respect to the coefficients of the equation.The schemes studied in refs.[1], [3], [4] and [5] belong to the cllass.
